LS2 FF901 Solid Full Face Motorcycle Helmet – ECE Approved, Dual Visor, Pinlock Anti-Fog, 180° Backflip

LS2 FF901 Solid Full Face Motorcycle Helmet – ECE Approved, Dual Visor, Pinlock Anti-Fog, 180° Backflip

The LS2 FF901 Solid stacks three visor systems into one helmet: a Class 1 polycarbonate outer clear lens with 3D optical correction; a retractable internal sun visor in UV-resistant polycarbonate that drops without removing the helmet; and Pinlock anti-fog technology using a multi-layer composite resin insert with a hollow air gap that eliminates the temperature differential causing fogging. The 180° backflip chin bar converts the full-face to a half-face configuration at the press of a switch, and dynamic aerodynamic ventilation adjusts airflow throughout. ECE approved, ABS shell, cotton comfort lining, M–3XL, one-year warranty.

✔ Key Features

ECE Approved: Independently lab-tested to ECE R22 — covering impact attenuation, retention strength, chin strap release, and field of view — not manufacturer self-declaration

Triple Visor System: Class 1 PC clear outer lens (3D optically corrected), an independent UV-resistant internal sun visor on a lever, and Pinlock anti-fog compatibility — no need to carry separate tinted and clear visors

Pinlock Anti-Fog Insert: A sealed hollow air gap and composite resin keep the lens clear through tunnels, fog, and sudden temperature changes where a single lens fogs immediately

180° Backflip Chin Bar: Rotates rearward to convert full-face to half-face without tools or dismounting, locking in both positions

ABS Shell + EPS Liner: Injection-moulded shell spreads impact force to the EPS liner, which absorbs energy through cellular crush

Dynamic Ventilation: Pushable crown and forehead intake vents channel air through internal ducting to rear exhausts — adjustable with gloves on

Back Closure Fit Adjustment: A rear dial draws the lining inward to fine-tune fit within each size band for firm, even contact

Cotton Comfort Lining: Soft moisture-managing interior; removable for washing

1-Year Warranty: Manufacturer warranty against material and construction defects

✔ Size & Fit Information

Available Sizes: M–3XL (Unisex)

Size Tip: Measure at the widest point of your skull — above the eyebrows, over the ears, and around the back. Take three readings and use the largest. Note this model starts at M (54–55cm), about 1cm smaller than most full-face helmets in its class. If you're between sizes, choose the larger and use the rear back-closure dial to fine-tune the fit within that shell size — if the closure is at maximum and the helmet still moves when rocked, the shell is too large. A correctly sized helmet feels firm and even with no gaps, and the liner conforms over the first 15–20 hours of use.
